A speculative, phenomenological model is formulated for the time-varying intensity and spread rate of a free-burning fire under the influence of nonsteady wind. The model is linearized by approximations and explicit solutions derived for the amplitude response of spread rate and…

Studies of the atmospheric dispersion over complex terrain, with the aid of smoke plumes, enable the direct observation of the marginal density probability of the emitted particles. Experiments near the ground correlate the turbulence easurements at 10 m height and plume…

'...With the aid of modern laboratory techniques it is possible to detect not only the end products of combustion proccsses but also many substances that appear transiently in the course of burning. As a result fire has come to be understood chemically as an intricate network of…

The relationship between daily total tons of forestry fuel consumed by prescribed burns in western Oregon and 24-hour average total suspended particulate (TSP) concentration in the Willamette Valley is examined. The relationship is statistically significant at the 95% level. A…

An empirical representation of the power spectral density of horizontal gustiness near the ground in high winds is combined with a theoretical model for the response of free-burning fires to nonsteady wind to predict the variability of spread rate and intensity of wind-aided…

From the text... 'To understand and predict wildland fire behavior, it is necessary to enlarge analogies drawn from confined fires and to create models for the components of the fire environment, such as fuels and weather, and for the mechanics of fire propagation. Wildland fire…
